Portion size and meal consumption in domesticated dogs: An experimental study
| Contributor(s):: Inge Kersbergen, Alexander J. German, Carri Westgarth, Eric Robinson
Increases in food portion sizes have been identified as a possible contributor to the increased prevalence of obesity in humans. However, little is known about the origin of behavioural tendencies to overeat from larger portion sizes or whether other non-human animals are affected by meal...
Synergistic effect of an ultraviolet feeding cue for an avian repellent and protection of agricultural crops
| Contributor(s):: Werner, Scott J., DeLiberto, Shelagh T., Pettit, Susan E., Mangan, Anna M.
Application strategies for avian repellents are needed to maintain efficacious repellent concentrations throughout the period of needed crop protection. We investigated the repellency of an ultraviolet (UV) feeding cue in the absence of postingestive consequences, the combination of the UV...
Social learning of feeding behaviour in pigs: Effects of neophobia and familiarity with the demonstrator conspecific
| Contributor(s):: Figueroa, Jaime, Solà-Oriol, David, Manteca, Xavier, Pérez, José Francisco
Social interactions facilitate animals learning of new features of their environment minimizing a trial and error process. It has been observed in some species that food cues can be acquired by one individual (the observer) from an animal model (demonstrator) due to social learning. Three...
Improved acceptance of Chromonaela odorata by goat kids after weaning is triggered by in utero exposure but not consumption of milk
| Contributor(s):: Hai, Phan Vu, Schonewille, Jan Thomas, Van Tien, Dam, Everts, Henk, Hendriks, Wouter Hendrikus
The aim of the current study was to determine whether the improved post-weaning intake of Chromonaela odorata by goat kids is related to either the in utero period of the goat kids or the subsequent suckling period. It was hypothesized that kids born to dams fed C. odorata during pregnancy and...
Improved acceptance of Chromonaela odorata by goat kids after weaning is caused by in utero exposure during late but not early pregnancy
The aim of the current experiment was to study the effect of the phase of pregnancy on in utero learning of Chromonaela odorata by the goat kids by comparing mid pregnancy (day 50–99, MP) with late pregnancy (day 100–145, LP). It was hypothesized that kids born to dams fed C. odorata during late...
Effects of signalled reward type, food status and a μ-opioid receptor antagonist on cue-induced anticipatory behaviour in laying hens (Gallus domesticus)
| Contributor(s):: Moe, Randi Oppermann, Nordgreen, Janicke, Janczak, Andrew M., Spruijt, Berry M., Bakken, Morten
Studies using classical conditioning have shown that hens display high frequencies of dopamine-controlled cue-induced anticipatory behaviours in the cue-reward interval when signalling mealworm rewards. However, it is not known whether anticipatory behaviours are reward specific, and whether the...
Can stealing cows distort the results of feeding trials? An experiment for quantification and prevention of stealing feed by dairy cows from roughage intake control feeders
| Contributor(s):: Ruuska, Salla, Hämäläinen, Wilhelmiina, Sairanen, Auvo, Juutinen, Elina, Tuomisto, Leena, Järvinen, Mikko, Mononen, Jaakko
Practical experience suggests that stealing behaviour of dairy cows may affect the results in feeding trials, when automated feed troughs are used for measuring and controlling the feed intake. The objectives of the present study were to analyse the stealing behaviour from the log data of the...
Behaviour in order to evaluate the palatability of pet food in domestic cats
| Contributor(s):: Becques, Aurélie, Larose, Claire, Baron, Céline, Niceron, Cécile, Féron, Christophe, Gouat, Patrick
Palatability of pet food has been mainly assessed by intake ratios. In the present study we have searched for behavioural clues of food palatability in domestic cats Felis catus. Two diets differing in palatability (Very Palatable Kibbles and Low Palatable Kibbles) were evaluated by a panel of 17...
Selection for wheat digestibility affects emotionality and feeding behaviours in broiler chicks
| Contributor(s):: Pelhaitre, Alice, Mignon-Grasteau, Sandrine, Bertin, Aline
In poultry farming, selection for high production, as for growth rate or feed efficiency, may be associated with risks for animal welfare. In this study, we tested whether divergent selection for a new trait linked to feed efficiency, i.e. digestibility, had correlated side effects on the...
Relationships between lameness and feeding behaviour in cubicle-housed Holstein–Friesian dairy cows
| Contributor(s):: Palmer, Maeve A., Law, Ryan, O’Connell, Niamh E.
The relationship between lameness and feeding behaviour in dairy cows is not yet fully understood. This study examined the effect of lameness on feeding behaviour at two points during lactation. Forty-five Holstein–Friesian dairy cows (average parity 3.3) were housed in cubicle accommodation...
Ration composition affects short-term diurnal feeding patterns of dairy heifers
| Contributor(s):: Greter, Angela M., von Keyserlingk, Marina A. G., DeVries, Trevor J.
The objective of this study was to compare the short-term (first week of adaptation to a new ration) behaviour of dairy heifers when fed a low-concentrate, high-forage ration ad libitum to when fed a high-concentrate ration in a limited amount followed by ad libitum access to straw for the...
Impact of single-sex and mixed-sex group housing of boars vaccinated against GnRF or physically castrated on body lesions, feeding behaviour and weight gain
| Contributor(s):: Schmidt, Tatjana, Calabrese, Justin M., Grodzycki, Mario, Paulick, Marleen, Pearce, Michael C., Rau, Franziska, von Borell, Eberhard
Physical castration of male piglets is common practice in many countries for the control of boar taint. A vaccine against GnRF (Improvac®) is licensed in Europe as an alternative to this painful procedure. Vaccinated pigs are known to behave like entire males up to the second vaccination,...
Feeding strategy in group-housed growing pigs of four different breeds
| Contributor(s):: Fernández, Josep, Fàbrega, Emma, Soler, Joaquim, Tibau, Joan, Ruiz, José Luis, Puigvert, Xavier, Manteca, Xavier
Feeding strategy was studied in 205 growing boars in two blocks of 116 and 89 pigs of four breeds (Large White, Landrace, Duroc and Pietrain) respectively. Pigs were housed in groups of 12–14 individuals, with a single breed in each group. Feeding patterns were recorded with a computerized feed...
Feeding Chromonaela odorata during pregnancy to goat dams affects acceptance of this feedstuff by their offspring
| Contributor(s):: Hai, Phan Vu, Everts, Henk, Van Tien, Dam, Schonewille, J. Thomas, Hendriks, Wouter H.
We investigated the effect of Chromonaela odorata ingestion by goat dams during pregnancy on intake of C. odorata by their kids. Alteration of prenatal feed preference may be used to increase feed intake of novel feeds and the transit from outdoor to indoor goat farming in Vietnam. Ten female...
Effect of fasting on self-feeding activity in juvenile sea bass (Dicentrarchus labrax)
| Contributor(s):: Benhaïm, David, Bégout, Marie-Laure, Péan, Samuel, Brisset, Blandine, Leguay, Didier, Chatain, Béatrice
In various experiments under self-feeding conditions, sea bass groups could be divided into three categories regarding feeder actuation: high, low and zero-triggering fish. In all cases few high-triggering fish were responsible for a high percentage of the feed delivery. A question was raised...

| Contributor(s):: Patbandha, Tapas Kumar, Mohanty, Tushar Kumar, Layek, Siddhartha Shankar, Kumaresan, Arumugam, Behera, Kumaresh
The present study reports the pre-partum behaviour of crossbred cows and the behavioural markers to predict the risk of developing post-partum metritis in this species. Dry pregnant crossbred cows (n=20) were observed continuously from 3 weeks before calving till the date of calving using video...
Anthraquinone repellent to reduce take of non-target birds from zinc phosphide rodenticide applications
| Contributor(s):: Werner, Scott J., Tupper, Shelagh K., Pettit, Susan E., Carlson, James C., Linz, George M.
We evaluated anthraquinone as an avian repellent to reduce take of non-target birds from zinc phosphide rodenticide applications. We observed zero mortalities and no overt signs of zinc phosphide toxicosis among 20 Canada geese (Branta canadensis), 24 horned larks (Eremophila alpestris), and 47...
